§ 17.17.020. Certificate of Occupancy.

  • A. The Building Official will not issue a final certificate of occupancy for an Accessory Dwelling Unit ("ADU") or Junior Accessory Dwelling Unit ("JADU") before the Building Official issues a final certificate of occupancy for the primary dwelling(s). Before the Building Official issues any final certificate of occupancy for an ADU and/or JADU, the property owner must record with the County Recorder a covenant, in a form approved by the City Attorney, satisfying applicable law, including this section.
